Detailed Description

Base class to implement a UNO object supporting weak references, i.e.

the object can be held weakly (by a css::uno::WeakReference). This implementation copes with reference counting. Upon last release(), the virtual dtor is called.

Derive: \n

Inherit from this class and delegate acquire()/ release() calls.
